The first total synthesis of both broussonetine I and J2 together with their enantiomers have been accomplished via the same synthetic route through 18 and 16 steps in excellent overall yields (18% and 19%, respectively), starting from R-glyceraldehyde. Broussonetine I was found to be a potent inhibitor of β-glucosidase (IC50 = 2.9 μM), while ent-broussonetine I and ent-broussonetine J2 were found
布鲁索汀I和J 2及其对映异构体的第一次总合成已通过相同的合成路线通过18和16步完成,从R-甘油醛开始,具有极好的总收率(分别为18%和19%)。发现Brossonetine I是β-葡萄糖苷酶的有效抑制剂(IC 50 = 2.9μM ),而ent -broussonetine I和ent -broussonetine J 2被发现是α-葡萄糖苷酶的有效抑制剂(IC 50 = 0.33和0.53μM , 分别)。
